In October 2018, the Office of Juvenile Justice and Delinquency Prevention (OJJDP) administered the 10th Juvenile Residential Facility Census (JRFC). JRFC began in 2000 with data collections occurring every other year. JRFC routinely collects data on how facilities operate and the services they provide. It includes questions on facility ownership and operation, security, capacity and crowding, and injuries and deaths in custody. The census also collects supplementary information each year on specific services, such as mental and physical health, substance abuse, and education. Nationally, 37,529 juvenile offenders were held in 1,510 residential placement facilities on October 24, 2018. Facilities that hold juvenile offenders vary in their operation, type, size, security features, screening practices, and services provided. To better understand the characteristics of these facilities, the Office of Juvenile Justice and Delinquency Prevention (OJJDP) sponsors the Juvenile Residential Facility Census (JRFC), a biennial survey of public and private juvenile residential facilities in every state. Findings in this bulletin are based on JRFC data collected for 2018.
